# POST /projects/{project}/global/networks

`POST /projects/{project}/global/networks`

Creates a network in the specified project using the data included
in the request.

## Path parameters

- `project` string, required

## Query parameters

- `requestId` string

## Request body

- Network — Represents a VPC Network resource. Networks connect resources to each other and to the internet. For more information, readVirtual Private Cloud (VPC) Network.
  - `mtu` integer — Maximum Transmission Unit in bytes. The minimum value for this field is 1300 and the maximum value is 8896. The suggested value is 1500, which is the default MTU used on the Internet, or 8896 if you want to use Jumbo frames. If unspecified, the value defaults to 1460.
  - `selfLink` string — [Output Only] Server-defined URL for the resource.
  - `autoCreateSubnetworks` boolean — Must be set to create a VPC network. If not set, a legacy network is created. When set to true, the VPC network is created in auto mode. When set to false, the VPC network is created in custom mode. An auto mode VPC network starts with one subnet per region. Each subnet has a predetermined range as described inAuto mode VPC network IP ranges. For custom mode VPC networks, you can add subnets using the subnetworksinsert method.
  - `peerings` NetworkPeering[] — Output only. [Output Only] A list of network peerings for the resource.
    - `updateStrategy` 'CONSENSUS' | 'INDEPENDENT' | 'UNSPECIFIED' — The update strategy determines the semantics for updates and deletes to the peering connection configuration.
    - `stackType` 'IPV4_IPV6' | 'IPV4_ONLY' — Which IP version(s) of traffic and routes are allowed to be imported or exported between peer networks. The default value is IPV4_ONLY.
    - `exchangeSubnetRoutes` boolean — Indicates whether full mesh connectivity is created and managed automatically between peered networks. Currently this field should always be true since Google Compute Engine will automatically create and manage subnetwork routes between two networks when peering state isACTIVE.
    - `connectionStatus` NetworkPeeringConnectionStatus — [Output Only] Describes the state of a peering connection, not just the local peering. This field provides information about the effective settings for the connection as a whole, including pending delete/update requests for CONSENSUS peerings.

        - `exportSubnetRoutesWithPublicIpToPeer` boolean — Whether subnet routes with public IP ranges are being exported to the peer network.
      - `consensusState` NetworkPeeringConnectionStatusConsensusState — The status of update/delete for a consensus peering connection. Only set when connection_status.update_strategy isCONSENSUS or a network peering is proposing to update the strategy to CONSENSUS.
        - `deleteStatus` 'DELETE_ACKNOWLEDGED' | 'DELETE_STATUS_UNSPECIFIED' | 'LOCAL_CANCEL_REQUESTED' | 'LOCAL_DELETE_REQUESTED' | 'PEER_CANCEL_REQUESTED' | 'PEER_DELETE_REQUESTED' — The status of the delete request.

    - `exportSubnetRoutesWithPublicIp` boolean — Whether subnet routes with public IP range are exported. The default value is true, all subnet routes are exported.IPv4 special-use ranges are always exported to peers and are not controlled by this field.
    - `autoCreateRoutes` boolean — This field will be deprecated soon. Use theexchange_subnet_routes field instead. Indicates whether full mesh connectivity is created and managed automatically between peered networks. Currently this field should always be true since Google Compute Engine will automatically create and manage subnetwork routes between two networks when peering state isACTIVE.
    - `network` string — The URL of the peer network. It can be either full URL or partial URL. The peer network may belong to a different project. If the partial URL does not contain project, it is assumed that the peer network is in the same project as the current network.
    - `exportCustomRoutes` boolean — Whether to export the custom routes to peer network. The default value is false.
    - `importSubnetRoutesWithPublicIp` boolean — Whether subnet routes with public IP range are imported. The default value is false.IPv4 special-use ranges are always imported from peers and are not controlled by this field.

The first character must be a lowercase letter, and all the following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.
    - `state` 'ACTIVE' | 'INACTIVE' — Output only. [Output Only] State for the peering.
